Details

Extension tubes are one method of getting closer with EF lenses. A powerful tool when attached to standard and wide-angle lenses, they’re also used with telephotos to get just a bit closer. With any lens, the longer the extension tube, the greater the close-up effect. The 12mm EF 12 II is often used with wide-angle lenses, while the longer EF 25 II is a better choice for normal or telephoto lenses. Auto exposure continues to work reliably, but manual focus is recommended in most instances.
